Ipomoea aquatica, commonly known as water spinach or kangkong, is a semi-aquatic, tropical perennial herb native to the the tropical and subtropical old world, including marshes, rice paddies, and waterways. It is characterized by its long, trailing stems that can reach up to 10 feet in length and its lush, green, lance-shaped leaves. The plant produces distinctive, trumpet-shaped flowers that are typically white or pale pink, blooming in the warm months of the year. Water spinach is not only ornamental but also edible, with a mild flavor that makes it a popular leafy green in Southeast Asian cuisine, used in dishes such as stir-fries and salads.

Water spinach thrives in full sun to part shade and requires constant moisture or even shallow standing water to grow, making it suitable for water gardens, ponds, and boggy areas. It is a fast-growing plant that can be easily propagated by stem cuttings. In cultivation, it is valued for its rapid growth and ability to cover large areas quickly, which can be beneficial for erosion control along water margins. However, due to its invasive nature in non-native regions, such as the southern United States, it is important to manage its spread responsibly and adhere to local regulations.CC BY-SA 4.0
